Force is applied to successive ones of the bodies in one region of the passageway to thereby propel the bodies around the passageway. The Seebeck coefficient is often incorrectly referred to as the thermoelectric power or thermopower (it is a voltage not a power). If AC power is required (such as for powering equipment designed to run from AC mains power), the DC power from the TE modules must be passed through an inverter, which lowers efficiency and adds to the cost and complexity of the system. Recent advances in materials science have increased this number to around 4. Without any temperature gradient . Waves convert mechanical energy to electrical energy. {\displaystyle \mathbf {J} =-\sigma S\nabla T}. All convert thermal energy to electrical current. Several patents about the use of thermoelectric devices in parallel or cascade configuration with solar cells have been filed.
